31 July 2012, Tests Scour Protection & Freespan Remediation completed at Deltares

 

GeoHooks, Anome Projects and Hydronamic completed a series of tests in the Atlantic bassin at Deltares. The aim was to prevent or repair erosion holes at offshore windmill posts and at pipeline freespan locations with GC layers.

 

In these scale tests many thousands of tiny 2 cm steel GC's were used.

 

Conclusions from the model testing:

- if an existing erosion hole is filled with a structure of GC's this hole will fill up to at least 70% with collected sand

- application of a GC layer around sensitive erosion spots (like scour areas around windmill posts or freespan areas at pipelines) will reduce the erosion effects substantially
